Trello is one of my freemium (free + premium AKA its free and rocks) tools that's I use to organize my biz.

I use Trello to organize projects and keep up with resources and tools quickly. Trello Gold allows you to upload more attachments and makes the experience more customized by allowing you to add various picture backgrounds and comment with emojis. Because emojis make life more fun.

I recommend Trello to all my visual lady friends. Trello is essentially a virtual white board for post-it notes.
